BOT'ILE-CLSURE.

Application tiled August 22, 1912.

'. Be it knownthat II, JOHNv P. Pnnssnn, a citizen of the United States, residing at Hamilton, in the county of Baltimoreand State of lllarvland, have invented certain new and useful lmprovements in Bottle- Closures, of which the following is a speci ltla lication.

This invention relates to improvements in bottle closures and has for its object to provide an improved device to be seated and secured in the neck of a bottle which will permit theready escape ot' liquid therefrom but which will effectuallyprevent the flow of liquid into the bottle to such extent as to render the latter operation commerciallyl irripracticable.

With the above object in view the' inventionis illustrated in the accompanying dra-wing, wherein,

Figure 1 1s a vertical sectional vview through the upper portion of a bottledand' the neck and 'also through the improved closure device therein. Fig'. 9.is a vertical sectional viewthrough the neck and closure the section however being taken in a diller ent vertical plane from that shown in Fig. l. Fie. is a perspective view ot the detached closure parts. Fig. 4, is a horizontal sectional view of the s: inie,--the` section being taken on the line 4--4 ot' Figfl, and Fig. 5, is a cross-sectional view of the same taken on the line Fi-- oli Fig. l.

The present invention is particularly au improvement on thev closure shown in the ll. S. Patent 1,006,874 granted to me ()cto.

YReferring to the drawing); b v numerals, l, iflesignates the lood7 ot a bottle; 2,-tlie neck thereof and, 3, a shoulder on the interior ot the neck tor a purpose presentl;7 to be explained.

The closure may be formed of any suitable material such as porcelain, glass or other substance that will not be all'ectcd by Contact with liquid and which will not taint or injuriously alter the liquid passing therethrough.v v

The closure hasl the form of a stopper in that. vit has a body, 1l, with a circular head, 5, at the upper end; a circular head, (3, at the lower end of slightly smaller dia-meter than the head at lthe upper, end and an intermediate body portion, 7, between said upper and lower heads.

heads snugly fit the interior of the bottle.

neck which latter is tapered to correspond to the diameters of the heads and thus a tight joint is produced between the heads` and neck wall to prevent-` lthe escape of liquitk From the foregoing explanation it will be obvious that each head is' tapered slightly and is larger around its4 upper edge than around its lower edge.

A partition. 8,'extends across the interior ot the stopper between the upper and/lower heads and forms an upper stopper chamber, l), and a lower valve chamber, l0. `The stopper' chamber extends `from the' upper side ot the partition to the upper edge of the upper head and the valve chamber extends troni the lower side of the partition to the lower edge of the lower head and is ite lolver edge. y

Y .i plurality of ports or passages, ll, ex-

tend laterally through the bodyY between the upper'head. and the partition, 8, and a plurality ot' ports or passages, la, extend laterally.through the body 'between the' lower head, (l, and the partition. Between the upper and lower setz-3 of ports, ll, and, 12. the intermediate body portions, 7, is provided with a plurality of separate'arid independent luga, i3. These lugs are spaced troni each other in longitudinal direction whereljiv to tormfvertieal or longitudinal passages, .l-l, between the two heads, and the upper ends ot the lugs are spaced troni the upper head lo form an upper cireinnterential passage, l5, while between the lower ot a` uniform diameter from its upper to.

ends and the lower head a cireumlerentialj passage, lli, is toi-ined. 'llheee circumferential passagree. l5. and, 1G, are therefore connected by' the vertical or longitudinal passages. let, so that communication between the lower ports. l2. and the upper ports, l1, may be establishedy around the said lugs, 13.

.fit valve-seat'disk` i7, is provided in the neck and sealed on the annular shoulder, il, and said disk has a central port, 18, with a beveled upper edge, 19, which is smaller than the lower end ot the longitudinal valve chamber, l0, and Ywhich connnunicates with the latter. B v means o't the valve-seat disk a ball valve, 20, may be retained in the valve chamber lo eil'ect. a closure between the latter and the bot-tlc neck;

The upper circular head, v5, is preferably provided with an annular groove, ,21,` in

which a filling of cement, 22, may be placed:

to secure the stopper in the neck. A cork stopper, 23, may be utilized to effect a closure of the mouth of 'the neck until the contents of the bottle is consumed.

,In the operation it will be seen that when the bottle is tilted to eifect'a dischargeof liquid, the ball will unseat 'romvalve seat, 19, which will admit the liquid to the valve chamber. will then fiowout through ports 12, to circumferential passage, 16;.then through longitudinal passages, 14, between the lugs, 13, to circumferential passages, 15 then through ports, 11, to stopper chamber, 9, and discharge; A reversal of the bottle will obviously cause ball-valve, 20, to Aclose the pas- From said chamber the liquid chamberl on4 the interior thereof and on the exterior said body being provided with a circumferential passage which has position about the upper stopper chamber and an- K other circumferential passage which has position about the lower chamber said two circumferential passages being spaced apart `and connected by exterior vertical passages,

between the lower interior chamber and the lower exterior circumferential passage said upper and lower ports being out of register with the said exterior vertical passages, and a valve yin the lower chamberA below said lower circumferential passage.

In testimony whereof I afiix my signature in presence of two witnesses.
